Tfans member Bumblerod has reported purchasing 6" Titanium Rodimus and Soundwave at a local store in the UK. You can see his posting here. He provides a mini review of each figure. However no photo evidence has been provided as of yet. So chalk this one up as rumor until confirmed.

In the meantime, if you need photos to appease yourself with, you can always take a look at Allspark Site Sponsor listings for either of these figures. You can find Ti Rodimus here and Soundwave here.
